The present invention relates to an exhaust gas after-treatment apparatus having improved durability. The exhaust gas after-treatment apparatus includes: an exhaust gas oxidation catalyst part for oxidizing an exhaust gas; an exhaust gas filtering part connected to the exhaust gas oxidation catalyst part to filter the exhaust gas; a selective catalyst reducing part connected to the exhaust gas filtering part; an ammonia oxidation catalyst part connected to the selective catalyst reducing part, wherein a first gas detection sensor for detecting a generated amount of an exhaust gas nitrogen compound introduced from the exhaust gas filtering part and a selective catalyst reducing bypass valve for selectively blocking the introduction of the exhaust gas into the selective catalyst reducing part are installed on a front side of the selective catalyst reducing part; and a control part electrically connected to the selective catalyst reducing bypass valve and the selective catalyst reducing part to control the operations of the selective catalyst reducing bypass valve and the selective catalyst reducing part on the basis of a gas amount detection signal.
